Question

What is the concentration of nitrate ions if equal volumes of 0.1 M $AgN{O}_3$ and 0.1 M NaCl are mixed together

• A. 0.1 M
• B. 0.2 M
• C. 0.05 M
• D. 0.25 M

Answer 1

The correct option is C 0.05 M

$0.1MAgN{O}_3$ will react with 0.1 M NaCl to form 0.1 M $NaN{O}_3$. But as the volume is doubled, conc. of $N{O}_3^{-}=\frac{0.1}{2}=0.05M$
